Arteries carry blood away from the heart.
Arteries carry blood away from the heart.
The correct answer is arteries.
To determine the structures that carry blood away from the heart, you will need a basic understanding of the circulatory system. Here's a step-by-step breakdown:
1. Start with the heart: The heart is a muscular organ responsible for pumping blood throughout the body. It consists of four chambers - two atria (left and right) and two ventricles (left and right), which work together to circulate blood.
2. Blood flow from the heart: The heart pumps oxygen-rich blood away from itself through a large vessel called the aorta. The aorta is the largest artery in the body.
3. Arteries: From the aorta, blood flows into smaller arteries. Arteries are thick, muscular blood vessels that carry oxygenated blood away from the heart and distribute it to various parts of the body. They have a strong and elastic structure to withstand the pressure generated by the heart's pumping action.
So, in summary, arteries are the structures that carry blood away from the heart.
